Chemical Structure
Description
The occurrence of 4-Chloro-N-(2,3-dihydro-1H-inden-5-yl)-2-nitrobenzenesulfonamide is closely related to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
4-Chloro-N-(2,3-dihydro-1H-inden-5-yl)-2-nitrobenzenesulfonamide (CAS 1022735-22-3), molecular formula C15H13ClN2O4S and molecular weight 352.79 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4-Chloro-N-(2,3-dihydro-1H-inden-5-yl)-2-nitrobenzenesulfonamide (C15H13ClN2O4S) is characterized by a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
